/* the lobby — a switch panel, not a dashboard.

 * The subject is marine instrumentation: this is a panel of breakers, one per
 * client, thrown by hand. Dark gunmetal by default because that is what an
 * instrument panel is; a brushed-aluminium daylight variant because the
 * operator is often outdoors in the Caribbean and a dark screen in that sun is
 * unreadable.
 *
 * Flat surfaces and hairline separators throughout. The only gradient in the
 * file is the lamp lens, which is the one place light physically belongs.
 *
 * No @font-face, no @import, no url() to anywhere. The CSP forbids it and the
 * VPS must never make an outbound request to render a page.
